Overview

VR-Training: Adapting Virtual Reality Training Applications by Dynamically Adjusting Visual Aspects
Author: Fabio Genz and Dieter Kranzlmüller

  • Survey: Cross-sectional study with longitudinal elements

  • 2 Cohorts (Linne and Dame)

    – 20 participants in Linne, 80 participants in Dame

    – 9 rounds of training for both cohorts

    – 2 rounds of test per cohort (Linne: VR, Dame: Real-world)

    – 3 groups of training versions: Adaptive, Non-Adaptive, Control

Terminology

Stress indicators:

  • Answer Q1: Perceived cognitive load (1 to 6 with 1 very low and 6 very high)
  • Answer Q2: Perceived physical load (1 to 6 with 1 very low and 6 very high)

Terminology

Physiological Measurement Data (PMD)

  • Heart rate (HR): Heart rate beats per minute (bpm)
  • IBI: Interbeat interval (ms)
  • SDNN: Standard deviation of the NN intervals
  • RMSSD: Root mean square of successive differences
  • SCL: Skin conductance level (µS (micro Siemens))
  • SCR frequency: Frequency of the skin conductance response
  • SCR amplitude: Amplitude/strength of the skin conductance response (µS/µmho (micro Siemens/micro Ohm))
  • SCR rising time: Rising time of the skin conductance response
  • Blink rate last minute: Blink frequency per minute
  • Saccade amplitude: Degree of eye movement
  • Saccade velocity: Speed of sudden eye movements
